IT architecture

The term IT architecture describes various aspects of information technology (IT) in an organization, e.g. B. the development of methodical IT specifications, models and guidelines. This serves the goal of developing a coherent IT architecture framework. In addition to formal and informal solution, business and infrastructure processes, modeling languages such as B. UML is used.

These include infrastructure ( hardware , locations, networks ), software (applications), technologies, interfaces, functions and processes supported by IT, as well as the associated architecture management (configuration and capacity planning , load distribution, data backup , availability , reliability, disaster scenario) Planning etc.).

An IT architecture describes the IT in an organization on two levels: It defines the basic structures and defines rules that coordinate the dynamic interaction of all components.

A widespread analogy compares an IT architecture with a development plan for urban planning . The development plan is essential as a central guideline for the people and groups involved in the construction and maintenance of the urban infrastructure. It ensures that the development of a city takes place in an orderly manner and that the resources available are taken into account. Similar to the development plan, the IT architecture provides guidelines for everyone involved in the planning and operation of IT systems and IT infrastructures. Accordingly, one speaks of a development plan when it comes to planning current and future IT architecture.
